Product Details

The Mikuni 4/042-540 is a precision-machined carburetor main jet designed for optimal fuel metering in Mikuni carburetors. This large hex-type jet features the traditional Mikuni hex head design for easy installation and removal with standard tools.

Key Features:

  • Large hex head design for secure grip and easy adjustment
  • Precision-drilled orifice for accurate fuel flow control
  • Compatible with most Mikuni carburetor models
  • High-quality brass construction for durability and corrosion resistance
  • Part of the Mikuni 4/042 series main jet family

Main jets are critical carburetor components that control the fuel flow at wide-open throttle and high RPM operation. The jet size number indicates the orifice diameter, allowing tuners to fine-tune fuel mixture for optimal performance across different atmospheric conditions, elevations, and engine modifications. This genuine Mikuni replacement jet ensures proper fit and reliable performance.
